Chapter 8: Q.13 (page 199)

Mass $m_{1}$ on the frictionless table of FIGURE EX8.13 is connected by a string through a hole in the table to a hanging mass $m_{2}$ . With what speed must $m_{1}$ rotate in a circle of radius $r$ if $m_{2}$ is to remain hanging at rest?
FIGURE EX8.13

Short Answer

Expert verified

The speed must $m_{1}$ rotate in a circle of radius $r$ if $m_{2}$ is to remain hanging at rest is

v = \sqrt{(\frac{m_{2}}{m_{1}}) r g}

Step by step solution

Given information

Given in the question that, Mass $m_{1}$ on the frictionless table of FIGURE EX8.13 is connected by a string through a hole in the table to a hanging mass $m_{2}$ .

FIGURE EX8.13

Explanation

Here,

Here

$F_{c} = F_{w}$

$F_{c} = \frac{m_{1} v^{2}}{r}$

$F_{W} = m_{2} g$

$\frac{m_{1} v^{2}}{r} = m_{2} g$

From the above equation we get,

$v = \sqrt{(\frac{m_{2}}{m_{1}}) r g}$

This is the speed must $m_{1}$ rotate in circle of radius $r$ if $m_{2}$ is to remain handing at rest

$v = \sqrt{(\frac{m_{2}}{m_{1}}) r g}$

Final answer

The speed must $m 1$ rotate in a circle of radius $r$ if $m_{2}$ is to remain hanging at rest is

$v = \sqrt{(\frac{m_{2}}{m_{1}}) r g}$
